69975 SNS-ABS-0002 A 13 2450.00 Broad Spectrum Active Sunspray 100ml Quick-absorbing broad spectrum sun spray Smart Sun Care. A lightweight, non-greasy active sunspray with broad-spectrum SPF 50+ PA++++ protection, powered by NAD+ to help defend against UVA, UVB and urban pollutants. This high performance formula hydrates, soothes and shields all in a single spritz. Apply generously to face, neck, arms, legs and all exposed skin. Dermatologist-tested and gentle enough for sensitive skin. This sunsprays primary mission is UV protection - which it aces. Hydration is moderate (its not a primary hydrator, but it does keep skin comfortable). While it doesnt treat pigmentation per se, by preventing sun damage it effectively stops new sun spots (hence we emphasize protection rather than reduction). Its preventative nature warrants high scores in firmness and wrinkles - consistent use will significantly slow aging. The added antioxidants and NAD+ give it high marks in resilience too. In summary: its protection now and investment for later, all in a very user-friendly form. 3.0000 Sun Care 2708 2813 61273 Beyond Beyond 2082.500000
